Chelsea Midfielder Willian: I must prove myself daily

Chelsea attacking midfielder Willian says he needs to prove his quality everyday to remain in Jose Mourinho’s first-team plan.
Willian impressed in the Blues’ 3-0 defeat of fellow Premier League side Aston Villa on Saturday.
"I think I have to prove myself on a daily basis while I’m at Chelsea, kill a lion each time, and I’m dedicated to that mission, to give my best," said the midfielder, as quoted by reliable Agen Bola indo11.com.
"The expres​sion(kill a lion) comes from Brazil; when I started playing my dad would use it all the time as a way of instilling confidence in me and showing that if you work hard every day results will occur."
